Commensal, gingivitis, and cariogenic biofilms regulate TLR expression differently. (A) Western blot analysis of TLRs 1-5 and 7-9 indicate the presence or absence of TLR proteins in RHG epithelium after 24 h biofilm exposure. (B) The TLR 2-7 mRNA expression after biofilm exposure. Data represent the average of three independent experiments (each with an intra-experiment duplicate) ± SD; *p < 0.05; **p < 0.01; ****p < 0.0001; one-way ANOVA followed by Bonferroni's multiple comparison for comparison between groups.
